Acetylene, which is the simplest alkyne hydrocarbon, exists as a colorless, flammable, unstable gas with a distinctive pleasant odor (acetylene prepared from calcium carbide has a garlic smell resulting from traces of phosphine produced in this process). The term acetylenes is used generically in ...

It has now been found in accordance with the invention that improved yields of nitrophenyl hydroxy substituted acetylenes can be prepared from nitrobromobenzene by reaction of the nitrobromobenzene with a substituted terminal acetylene compound containing at least three carbon atoms and a hydroxy group ...
It has now been found that a poly(acetylene) having a higher density and a markedly different morphology can be produced from the same or similar precursor polymers under appropriate conditions. Accordingly, the present invention is a ... DC Bott,John H. Edwards,William J. Feast - US 被引...
1,3,2-Dioxathiole 2-oxides have been prepared from the reaction of enediols with thionyl chloride 〈66HC(21-1)1〉. (34) Alkyl-substituted 1,3,2-dioxathiolane 2,2-dioxides may be prepared by methods similar to those described in Section 4.15.7.2.1 for the preparation of the parent ...

It was prepared by a reaction, discovered by Friedrich Wohlerthe in 1862. The hydrolysis of calcium carbide reaction can be given as follows: \[ CaC_{2} + 2H_{2}O → Ca(OH)_{2} + C_{2}H_{2} \] The reaction represented above takes place at an extremely high temperature, approxi...
Trimethylsilylacetylene can be obtained commercially or prepared by deprotonating acetylene with a Grignard reagent and subsequently adding trimethylsilyl chloride. An alternative reagent, 2-methylbut-3-yn-2-ol, can also be used for alkynylation and deprotection with base. ...
(TRIISOPROPYLSILYL)ACETYLENE is a colorless transparent oily liquid. It can be prepared by a one-step reaction of triisopropylsilane bromide with acetylene gas. Literature reports suggest its use in the synthesis of an intermediate for Pitavastatin J. ...
